스프링클러 설비는 화재시 건물의 실내 천장에 설치된 스프링클러 헤드로부터 자동적으로 물이 분사되어 방사상으로 쏟아져 내리면서 화재를 진압함과 동시에 화재가 발생한 것을 알리는 자동소화 설비이다.The sprinkler facility is an automatic fire extinguishing facility that automatically extinguishes the fire by spraying water from the sprinkler head installed on the indoor ceiling of the building and pours it down radially in case of a fire, and notifies that a fire has occurred.

이러한 스프링클러 설비의 스프링클러 헤드는 천장에 노출된 상태로 설치되며, 소화액, 즉 소화용 급수의 배관과 연결되어 화재 발생시 전술한 배관의 단부가 열리면서 소화용 급수의 배관으로부터 공급되는 소화액이 방출되도록 하는 것이다.The sprinkler head of such a sprinkler facility is installed in a state exposed to the ceiling, and is connected to the fire extinguishing liquid, that is, the pipe of the water supply for fire extinguishing, so that when a fire occurs, the end of the pipe is opened and the fire extinguishing liquid supplied from the pipe of the fire water supply is discharged. .

이러한 스프링클러헤드는 소화액의 공급배관에 결합된 소화액 배출관과, 주변온도가 설정된 온도 이상으로 상승될 때 그 배출관을 개방시키는 감열개폐수단 과, 개방된 소화액을 분산시키는 디플렉터로 이루어져 있다.This sprinkler head is composed of a fire extinguishing liquid discharge pipe coupled to the supply pipe of the fire extinguishing liquid, a thermal opening and closing means for opening the discharge pipe when the ambient temperature rises above a set temperature, and a deflector for dispersing the opened fire extinguishing liquid.

그런데 상기 디플렉터는 외부로 소화액을 분산시켜 건물 내의 화재를 조기 진압하는데 용도로 사용되고 있으나, 디플렉터가 고정형으로 설치되는 경우에는 분사패턴이 균일하지 못한 단점이 있다.However, the deflector is used for early suppression of fires in buildings by dispersing the extinguishing liquid to the outside, but when the deflector is installed in a fixed type, there is a disadvantage that the spray pattern is not uniform.

이와 관련하여 대한민국 공개실용신안공보 실2000-0000531호(2000.01.15)에는 중앙에 통공이 천공된 디플렉터를 머리부와 일체인 프레임의 하단에 나사홈이 천공된 지지구의 외측으로 삽입한후 리벳팅하여 일체가 되도록 고정되게 구성한 스프링클러헤드의 디플렉터에 있어서, 상기 프레임 하단의 지지구에 천공된 나사홈으로 디플렉터의 중앙에 돌출형성한 돌기나사를 나사식으로 결합할 수 있도록 구성한 것을 특징으로 하는 '스프링클러헤드의 디플렉터'가 개시된 바 있다.In this regard, Korean Utility Model Publication No. 2000-0000531 (2000.01.15) states that a deflector with a hole in the center is inserted into the outside of a support hole with a threaded groove at the bottom of the frame integral with the head, and then riveted. In the deflector of the sprinkler head configured to be fixed to be integrated, the sprinkler is configured to be screwed with a protruding screw protruding in the center of the deflector with a screw groove drilled in the support hole at the bottom of the frame. Head deflector' has been disclosed.

따라서, 상기 디플렉터(50)가 고정판(61)의 상부에서 소정의 높이로 이격되어 회전되는 것이 가능하게 되는 것이다.Accordingly, the deflector 50 can be rotated apart from the top of the fixing plate 61 to a predetermined height.

아울러, 본 발명에 따르면 상기 밸브체(20)가 이탈되어 방수구(11)를 통해 분사되는 물이 디플렉터(50)와 충격하여 비산하되, 상기 디플렉터(50)가 수압에 의해 회전함으로써 난반사가 이루어져 고른 분사패턴을 얻을 수 있게 되는 것이다.In addition, according to the present invention, the valve body 20 is separated and the water sprayed through the waterproof opening 11 impacts and scatters the deflector 50, but the deflector 50 rotates by water pressure, resulting in diffuse reflection. It is possible to obtain a spray pattern.

본 발명은 상술한 실시 예에 한정되지 않으며, 본 발명의 사상을 해치지 않는 범위 내에서 당업자에 의한 변형이 가능함은 물론이다. 따라서, 본 발명에서 권리를 청구하는 범위는 상세한 설명의 범위 내로 정해지는 것이 아니라 후술되는 청구범위와 이의 기술적 사상에 의해 한정될 것이다.It goes without saying that the present invention is not limited to the above-described embodiments, and modifications by those skilled in the art are possible within the scope of not impairing the spirit of the present invention. Therefore, the scope of claiming the rights in the present invention is not defined within the scope of the detailed description, but will be limited by the claims and the technical spirit thereof to be described later.
